First multiple both sides by 4 = 12k^2+29k-1000, rewrite it 12k^2+125k-96k-1000=0, factor k out from the expression k x (12k+125)-96k-1000=0, then factor out 8 k x (12k+125)-8(12k+125)=0, factor out 12k+125 to (12k+125)x(k-8)=0, now when the product of factors equals 0, at least one factor is 0 - 12k+125=0 k-8=0, solve the equation for k k=-125/12





k=8

Divide (–15x5 – 16x4 + 84x3 – 17x2 – 9x – 15) by (x – 8/5) using synthetic division.
xz_007 [3.2K]
Synthetic division work with the coefficient of the given polynomial expression

We have 
-15    -16   84   -17   -9   -15

and the divisor is:
x - ⁸/₅ = 0
x = ⁸/₅

Refer to the diagram below for the steps of synthetic division

Start by multiplying the first coefficient by the divisor, write the answer under the second coefficient, and then add the two values.

Repeat the steps until we use up all the remaining coefficients

The final values are the coefficients of the quotient and the last value is the reminder

If you have 2 different slopes what is true about the slopes
Anna007 [38]

Answer:

Step-by-step explanation:

If two lines have different slopes, they cannot be the same line. If they share a y-intercept, that means they cross the y -axis at the same y value.  If they share an x value and corresponding y value, they intersect at that point, in this case their y-intercept.

Hope this helped!!

A farmer was counting his chickens and pigs. He had 16 animals in all and counted 54 legs. How many chickens does he have
Vikentia [17]

Answer:

5 chickens

Step-by-step explanation:

Let's set chickens and pigs with variables "c" and "p" respectively.

We know there a 16 animals in all, so there are:

c+p=16

We know there are 54 legs and chickens have 2 legs and pigs have 4 legs each:

2c+4p=54

Now we have our system of equations:

c+p=16

2c+4p=54

We are trying to find the number of chickens, so we write the first equation in respect to c.

p=16-c

Substituting the first derived equation to equation two:

2c+64-4c=54

Simplifying:

64-2c=54

2c=10

c=5

So there are 5 chickens.
